Cruise control is a system, which automatically controls the speed of your vehicle according to the settings by the driver. There are two types of cruise control systems, which comes in vehicles, electronic cruise control and adaptive or radar cruise control. Audi A7 comes with Adaptive cruise control system which helps in maintaining a set distance from the vehicle in front. The technology uses radar sensors to measure the distance from the vehicle and reduces throttle as the distance decreases. It also can apply brakes when the distance is excessively reduced. As the distance increases, it increases the speed automatically. The system is beneficial at the matter of safety.
